PostgreSQL pg_is_other_temp_schema() Function

The PostgreSQL pg_is_other_temp_schema() function checks whether the specified OID is the OID of another session’s temporary schema.

pg_is_other_temp_schema() Syntax

Here is the syntax of the PostgreSQL pg_is_other_temp_schema() function:

pg_is_other_temp_schema(oid) -> oid

Parameters

oid

Required. The OID to check.

Return value

The PostgreSQL pg_is_other_temp_schema() function checks whether the specified OID is the OID of another session’s temporary schema, and returns TRUE or FALSE.

pg_is_other_temp_schema() Examples

First, let’s create a temporary table with the following statement:

CREATE TEMPORARY TABLE test (id INT);

Then, look at the OID of the temporary schema for the current session :

SELECT pg_my_temp_schema();

 pg_my_temp_schema
-------------------
             17380

In the current session, we use to pg_is_other_temp_schema() check if the OID 17380 is the OID of the ephemeral schema of another session:

SELECT pg_is_other_temp_schema(17380);

 pg_is_other_temp_schema
-------------------------
 f

Here, the pg_is_other_temp_schema() function returns f(FALSE). Because 17380 is the OID of the temporary schema of the current session, not the OID of the temporary schema (Schema) of other sessions.

Let’s open a new session, executing the pg_is_other_temp_schema() function:

SELECT pg_is_other_temp_schema(17380);
